A new study discovers that drinking even a small portion of an alcoholic drink, wine, beer or hard liquor, on a daily basis increases the risk of developing breast cancer.

To better understand the relationship between alcohol and the risk of breast cancer, a team of scientists evaluated data from 10 previous studies that included pre-menopausal women and 22 studies with post-menopausal women.

Their analysis showed solid evidence that drinking the equivalent of a small glass of wine or beer daily increases the risk of pre-menopausal breast cancer by 5%, and in post-menopausal women by 9%.

Lead author Dr. Anne McTiernan says: “We tried looking separately at beer, wine, and spirits, but none jumped out as being more or less problematic. They all showed the same trends.”

The research found that 873 participants that became obese with mathematical modeling showing drinking a glass of water instead of a fizzy drink or a beer a day the risk of obesity by 20%. Swapping a sugar-sweetened beverage with water was connected to the 15% lower risk of developing obesity.
